\HONING" Staci Specification of Letters Patent.

Patented July 31, 1906.

Application filed November 28, 1904. Serial No. 234,527.

To all whom it may concern} Be it known that I, GEORGE R. CRAW, acitizen of the United States, and a resident of Chicago, in the countyof Cook and State of Illinois,have invented certain new and usefulImprovements in Honing-Strops, of which the following is a full, clear,and exact description.

My invention relates more particularly to a strop for honing or puttinga fine sharp edge on razors, although, obviously, it may be used forsharpening other kinds of cutlery.

The object of my invention is to provide a simple, cheap, and effectivehoning-strop the use of which greatly reduces the' time required tosharpen and put a smooth keen edge on the razor. This I accomplish bythe means hereinafter fully described, and as particularly pointed outin the claims. In the drawings, Figure 1 is a plan view of a section ofmy improved honing-strop. Fig. 2 is a similar view of a still smallerportion, Fig. 3 is a longitudinal section thereof, taken on line 3 3,Fig. 2. Fig. 4 is an end view of the die used in forming the depressionson the surface of my improved strop.

In the drawings, A represents a strop, of leather or other suitablematerial, preferably of the same width and length as an ordinaryrazor-strop. One side of this strop is smooth;

rically-arranged depressions a, by means of a cylindrical or other dieB, as shown in Fig. 4. This die is provided with series of crisscrossserrations which leave its circumference covered withsymmetricallyarranged pointed teeth in relief, which when utilized tomake its impression on the strop leave crisscross ridges c and d,substantially as shown. When the razor is drawn over this ridgedsurface, so

the blade to and off of its cutting edge, the ridges cause a frictionfirst away from a given point and then toward it, and this action takesplace throughout the entire length of that portion of the cutting edgeof the blade in contact with the strop. While the plaindressed leather,ridged in the manner described, will do excellent work, I prefer to givei instance, finely-powdered Whetstone or othersharpening material-whichgreatlyincreases its effectiveness. While I much prefer to arrangethedepressions in the surface of the strap symmetrically, as shown, yetthe arranging of said depressions in any other manner would answer thepurpose, although perhaps not so well.

What I claim as new is 1. A strop consisting of a flexible strap havingthe surface of one side thereof rovided with indentations; and ridges melate the same, said ridges intersecting each other.

2. A strop consisting of a flexible strap having the surface of one sidethereof provided with symmetrically-arranged indentations; and ridgesmediate the same, said ridges intersecting each other.

3. A strop consisting of a flexible strap having the surface of one sidethereof pro vided with symmetrically-arranged indentations that producecrisscross ridges mediate the same, said ridges intersecting each other.

4. A strop consisting of a flexible strap having the surface of one.side thereof provided with indentations; ridges mediate saidindentations, said ridges intersecting each other, and a coating ofabrasive composition applied thereto.

5. A strop consisting of a flexible stra having the surface of one sidethereof provided with symmetrically-arranged indenta tions; ridgesmediate said indentations,- said ridges inter'secting each other and acoating of abrasive composition applied thereto.

6. A strop consisting of a flexible strap having the surface of one sidethereof provided with symmetrically-arranged indenta tions that producecrisscross ridges mediate the same, said ridges intersecting each other;and a coating of abrasive composition applied thereto.

7. A strop consisting of a flexible strap having the surface of one sidethereof provided with symmetrically-arranged indentations that producediagonal crisscross ridges mediate the same. said ridges intersectingeach other.
